This is a dataset of 32 five-second-long vibration recordings. One human used a metal tool to perform one of two tool-mediated surface interactions (tapping or dragging) on the following four different surfaces: sandpaper (hard and rough), acrylic plastic (hard and smooth), rough paper (soft and rough), and rubber (soft and smooth). Each of the eight combinations of interaction and surface were recorded four times.

PMDC motor finds wide application in electric unity systems. Performance of the motor depends on overall mechnical vibrations. These two aspects are inter related. Also the structural platform or foundations play important role in these regards. Too much vibration often cause short circuit for short period. This data set presents sample vibration dependent short circuit data of current signals along with normal current for a PMDC with 12 volt supply.   

Instructions: 

Data set includes Normal current data in column 1 and the two sets of short duration fault data that occurs due to the vibtrations of motor and foundations propagated to circuit connections causing the shrt circuit. If vibration is minimized, they will not occur.

This dataset contains multimodal sensor data collected from side-channels while printing several types of objects on an Ultimaker 3 3D printer. Our related research paper titled "Sabotage Attack Detection for Additive Manufacturing Systems" can be found here: https://doi.org/10.1109/ACCESS.2020.2971947. In our work, we demonstrate that this sensor data can be used with machine learning algorithms to detect sabotage attacks on the 3D printer.
